Oculus Rift virtual desktop gone

[Elaphe]

This problem never happened to me before, but some weeks ago I experienced it and now it happens very often, usually after the first race. The virtual desktop, neeed to use Content Manager with your headset on simply dissapears. This is very annoying, specially because it forces you to grab the Oculus controller and open again the virtual desktop from the Oculus dashboard. Before this problem appeared I only had to do this once, before running Content Manager. Then I could leave the controllers on my desk and forget completelly about them, since they were no longer neccesary. Any idea how to fix this? Thanx.
